Features of CGI:

  • CGI can be used to build a library of props, which can be reused if needed.
  • Without supplying the actual products, the highest quality room sets and illumination can be achieved.
  • Is one of the best and cost-effective methods when it comes to developing images and videos for electronic media like movies, video games, etc.
  • CGI is created with help of wireframe models. The properties like reflection, illumination can be assigned and modified to these wireframe models.
  • The quality of the visual effects is higher and more pronounced and controllable compared to physical ones.
  • Allows creation of images and effects which may not be feasible using other methods.
  • CGI is far safer than physical effects.
